SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Guide
261230001E1-5E
Introduction
This guide provides procedures for the following SHDSL 2-Wire/4-Wire NTU modules in the
series.
Note: The 6540 and 6541 model sets are separate AC or DC powered versions of the same base product (for example,
P/Ns 1230001 and 1230002; 1230007 and 1230008).

Description
The SHDSL 2-Wire/4-Wire NTU provides an interface between the SHDSL network and the
user Data Terminal Equipment (DTE). It supports applications such as LAN-to-LAN bridging,
Frame Relay circuit, and PABX termination. The SHDSL 2-Wire/4-Wire NTU can be used as
either of the following:
• remote unit to the ADTRAN Total Access®3000 multiservice platform (see Figure 1), or
• pair of units in a point-to-point limited distance campus configuration (see Figure 2), with
one SHDSL 2-Wire/4-Wire NTU configured to “LT” mode.

SHDSL 2-Wire/4-Wire Mode, Line Rate
The SHDSL 2-Wire/4-Wire NTU supports multi-rate line operation (refer to Table 3).
Table 3. 2-Wire/4-Wire Multi-Rate Operation
Data Rate Type 2-Wire Mode 4-Wire Mode
SHDSL Line Aggregate Data
Rate
200 kbps to 2.312 Mbps (N 64
kbps + 8 kbps, where N = 3 to 36)
In 2-wire mode, 8 kbps of band-
width is required for overhead
framing
400 kbps to 4.624 Mbps (N 64
kbps + 16 kbps, where 2 x N = 3
to 36)
In 4-wire mode, 16 kbps is
required for overhead framing.
Payload Data Rate 192 kbps to 2.304 Mbps (N 64
kbps, where N = 3 to 36)
384 kbps to 4.608 Mbps in 4-wire
mode (2 x N 64 kbps, where N
= 3 to 36)
Service Data Rate 64 kbps to 2.304 Mbps (N 64
kbps, where N = 1 to 36)
64 kbps to 4.608 Mbps (N 64
kbps, where N = 1 to 72)
This is the actual user data rate
delivered to either the G.703 or
Nx64 kbps ports.

Front Panel Push Buttons
There are four push buttons on the SHDSL 2-Wire/4-Wire NTU front panel (refer to Table 5).
The push buttons are recessed to avoid accidental actuation and can be disabled, either
individually or as a group, using the management interface.
Table 5. Front Panel Push Buttons
Push Button Description
PORT SELECT Press the PORT SELECT button to select the active port. Selection choices
cycle through the following order: No Port, Nx64k, G.703, SHDSL.
LOCAL LOOP /
ERR INJ
If a port is selected, and a Bit Error Rate Test (BERT) is not in progress, press
the LOCAL LOOP/ERR INJ button to initiate or terminate a local loop on the
selected port. If a BERT is in progress, press the button to inject a single bit
error.
REMOTE LOOP If the SHDSL port is selected, press the REMOTE LOOP button to either place
or remove a remote loop on the port by sending a EOC request message to the
LTU (or NTU in campus mode). If the Nx64K port or G.703 port (with only
one service defined) is selected, press this button to place or remove a remote
loop on the selected port's single data service by sending respective inband
loop up or loop down patterns to the far end (in the associated data service
timeslots).
BERT If a port is selected and there are no local loops, press the BERT button to start
or stop a BERT on the selected port.
